Numbers 30:3-5

3Also when a woman voweth a vow unto Jehovah, and bindeth herself by a bond, being in her father’s house, in her youth, 4and her father heareth her vow, and her bond wherewith she hath bound her soul, and her father holdeth his peace at her; then all her vows shall stand, and every bond wherewith she hath bound her soul shall stand. 5But if her father disallow her in the day that he heareth, none of her vows, or of her bonds wherewith she hath bound her soul, shall stand: and Jehovah will forgive her, because her father disallowed her.
